I bought WP Reset (5 codes) for two reasons - ERS and Snapshots.

The ERS is a clever idea. As I often troubleshoot websites, I'm sure it'll save my butt in the future. The script is already pretty robust in what it can do. Any future tweaks will be gravy.

Snapshots is the biggest reason I bought this. I previously used UpdraftPlus for its auto-backup feature; however, I hate that it packages entire plugins upon update. A quick snapshot of the database, as WP Reset does, is all that's needed. With that said, my databases have been growing quite large lately. I hope future releases can skip storing the database copy in the database and instead save it to file (and automatically push to the cloud).

In all, I'm happy with WP Reset and recommend it!
